Let us discuss fuel rail distribution over actual injectors?
Because the factory rail spits fuel like crap, especially after 300~WHP.
Proven on car with a certain blue car with a couple burnt pistons when it was getting enough fuel and injectors were no where near static.
Pro tip #1: Anyone planning on higher HP builds, need billet logs or an equivalent.
Pro tip #2: Lucas 42.5's are better than stock when they are able to even distribute fuel and not be choked out by certain areas of the rail, IE all the bends by the FPR.
Then lets talk injectors. Start with the source of the problem and work your way down.
